Helping turn “what if” into “what is”
Task Management Tool: HowFull
HowFull is an application that helps you manage the tasks necessary to achieve your goals.
Start by setting the goal you want to accomplish. Then, break it down into smaller, actionable tasks and assign start and end dates to each one.
Daily tasks are shown in a “Today’s To-Do List,” allowing you to check them off as you complete them and visualize your progress.
For example, once a week, you reflect on your progress—what went well and what challenges you faced—and then plan for the week ahead.
After completing all tasks, you review the entire process again, recording your achievement level and insights for future improvement.
By supporting this step-by-step process, HowFull enables you to steadily and consistently move toward your goals.
